****Two primary forms of mercury are ethylmercury (inorganic mercury) which is primarily from dental amalgams, and methylmercury (organic mercury), which is they type found in fish.. In terms of toxicity, ethylmercury rates the highest. Methylmercury penetrates your body very well, but is slightly less toxic than the inorganic form, which is what you absorb from your dental amalgams.

****The two primary sources of mercury exposure are dental amalgam, and fish consumption, followed by thimerosal-containing vaccines, and mercury pollution from coal-burning power plants.
